The present thesis deals with a deep analysis of the genetic structure of extant human worldwide populations, with a special focus on the Mediterranean. Different genetic markers, 18 Alu insertions and 367 single nucleotide polymorphisms (SNPs), were analysed for the first time in general populations and Bedouins from Jordan. The same SNPs were also genotyped in a consistent set of samples from…
We’ll begin with a brief introduction to the two main types of stem cells, embryonic and adult stem cells. We’ll then discuss stem cell potency. The second section “Stem cells in research and diseases management” will focus on the opportunities and roles of stem cells in diseases and medical research. Stem cells have a special position in contemporary biological sciences due to their…
This module provides you with the foundational knowledge you need to understand what 'products' are, and how they can be classified, designed, produced and disposed of in ways that best preserve and promote the integrity of the environment, and of human health and safety. This module should take you about six hours to complete, including the time you will need to complete the activities and se…
Scientists deserve public recognition. The ways that they are depicted, however, are severely limited in physical and personal traits, helping to establish and enhance stereotypes under the general title of ‘scientist’. These stereotypes range from the arrogant researcher who wants to rule the world, to the lab coat wearing ‘nerdy’ genius, but all generally fall to an extreme view of an…
Pebbles are usually found only on the beach, in the liminal space between land and sea. But what happens when pebbles extend inland and create a ridge brushing against the sky? Landscape in the Longue Durée is a 4,000 year history of pebbles. It is based on the results of a four-year archaeological research project of the east Devon Pebblebed heathlands, a fascinating and geologically unique l…
Biology for AP® Courses covers the scope and sequence requirements of a typical two-semester Advanced Placement® biology course. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology for AP® Courses was designed to meet and exceed the requirements of the College Board’s AP® Biology framework while allowing signifi…
Agriculture has suffered enormous changes since the first human attempts to domesticate plants to obtain productive varieties which could become a constant source of food. Many developments have shaped current agricultural systems, especially those that led to extensive industrial monocultures. Concurrently with those, there are numerous other types of small scale agricultural systems with an i…
Social media and humans exist in a world of mutual influence, and humans play central roles in how this influence is mediated and transferred. Originally created by University of Arizona Information scholar Diana Daly, this Third Edition of the book Humans are Social Media uses plain language and features contributions by students to help readers understand how we as humans shape social media, …
This book presents the deterministic view of quantum mechanics developed by Nobel Laureate Gerard 't Hooft. Dissatisfied with the uncomfortable gaps in the way conventional quantum mechanics meshes with the classical world, 't Hooft has revived the old hidden variable ideas, but now in a much more systematic way than usual. In this, quantum mechanics is viewed as a tool rather than a theory. Th…
